I bought this laptop brand new back in December and the fans have started to make a slight rattling noise after starting up and sitting idle. Under heavy use, the laptop fans seem to run just fine and cooling doesn't seem to be an issue as the temperatures never get too high even when running on turbo. Everywhere I've looked up about rattling fans thus far has said it could be a bearing issue, but I haven't seen any threads about this model having this issue. I don't particularly want to have to ship out my laptop while we're dealing with Covid-19, because I'm reliant on my laptop. Any advice?

    Yes! Sorry for the delayed response. Preparing for finals took my focus for a few days. I'll provide a link. https://www.youtube.com/watch?v=JO-l8tuz1kg
    It may be a little hard to hear, but there's a rattling when idle or running a light load. I also kick the fan into max speed to compare. Thanks for the response!
  • have you checked if the air vents and fans are dusty?

    But, This is normal we can hear some cracking or rattling noise when fan speed is slow.
    Also we can only hear when there is full of silence and put our ears on laptop.

    Left side will be making sound a little more than right side fans


    This sounds comes from all laptop.
    Every type of fan create some noise when speed is slow

    @egydiocoelho I've sprayed out the vents with canned air several times

    @GAMING6698 Yeah, it was hard to hear in that video. The sound is more prominent in this one I took today. https://www.youtube.com/watch?v=pyq8DL6R6_g 
    I know that the fans were dead-silent when I first bought this. If the issue is due to just a few months of dust build-up, I'd be very surprised. 
  • I would try to clean the fans superficially. but you need to be a little careful when opening the notebook.

    egydiocoelho So the rattling sound in the fan on my Acer laptop has only gotten worse with time, as I suspected it would. Only the CPU fan is affected, where it will never reach max speeds, if it even turns on and it makes a soft, grinding noise. The GPU fan, by contrast, is in perfect condition. In fact, I'm concerned now that my GPU fan will wear faster having to compensate for my CPU fan. It's not a dirt buildup issue, as I've taken the laptop apart several times now to clean the fans by hand. The bearing on my CPU fan is faulty, which I have confirmed by the fact that the CPU fan blade spins with heavy resistance while the GPU fan spins effortlessly and silently. The only question now is what is the model of fan that I need to purchase to replace the CPU fan?
